Across
  1. 2. The range of wavelengths or frequencies over which electromagnetic radiation extends.
  2. 4. An educated guess
  3. 6. The interference that occurs when two waves combine to make a wave with a larger amplitude.
  4. 8. (f=ma) The acceleration of an object is the same direction as the net force of all objects is the same direction as the net force on the object
  5. 10. The total kinetic and potential energy of all the particles of an object
  6. 12. A wave that requires a medium through which to travel
  7. 14. The transfer of thermal energy between materials by collisions of particles.
  8. 15. In an experiment, a variable that does not change as the other variables change
  9. 17. Occurs when two or more waves meet while traveling along the same medium.
  10. 18. Mass per unit volume of material
  11. 23. Resistance of an object to a change in velocity
  12. 24. The amount of energy that flows through a certain area in a specific amount of time
  13. 25. The energy of stretched or compressed objects
Down
  1. 1. a=(vf-vi)/T
  2. 3. The distance and direction of an objects change in position from the starting point.
  3. 5. Attractive force between two objects that depends on the masses of the objects and the distance between them
  4. 7. Rhe science that focuses on planet Earth and its place in the universe
  5. 9. The bouncing back of a wave when it hits a surface through which it cannot pass.
  6. 11. A change from one form of energy to another (also called an energy conversion)
  7. 13. The movement of fluids in a cycle because of convection.
  8. 16. The movement of thermal energy from a warmer object to a cooler object.
  9. 19. Rhythmic disturbance which carries energy through matter or space.
  10. 20. Unit used to measure frequency
  11. 21. Reflection from a rough surface
  12. 22. The bending of a wave as it enters a new medium.
